Hi,
I am using version 0.94.14 and I am trying to merge KeyValues of 2 results
into 1 result.
Basically somewhere in time I cache a keyvalue of a result:
### Putting in cache KeyValue with key:
\x00\x09\x00\x00\x00\x04\x00\x00\x00\x00\x07\x011c\x00\x00\x01B\xE2\xE0\x0C\xEF\x04,
tableName: STOCK, Family: 1, Qualifier: c, Value: ^@^@^@3
Later I get that KeyValue from my cache and add it to a list
(List<KeyValues> kvs). Then I add some more KeyValues from a Result
instance to that list:
kvs.addAll(partialResult.list());
Collections.sort(kvs, KeyValue.COMPARATOR);
Finally, I build a new result with all those KeyValues ( new Result(kvs) ).
When I iterate through the map of that result I can read all values
correctly:
for (byte[] f : result.getMap().keySet()) {
System.out.print("### Result2 Family: " +
Bytes.toString(f));
for (byte[] q : result.getFamilyMap(f).keySet()) {
System.out.print(" : Qualifier: " + Bytes.toString(q) +
" :: Value: "
+
Bytes.toString(result.getFamilyMap(f).get(q)));
}
System.out.println();
}
But if I try to get values using result.getValue(...):
for (byte[] f : result.getMap().keySet()) {
System.out.print("### Result Family: " + Bytes.toString(f));
for (byte[] q : result.getMap().get(f).keySet()) {
System.out.print(" : Qualifier: " + Bytes.toString(q) +
" :: Value: " + Bytes.toString(result.getValue(f, q)));
}
}
I only get the 2 first values, others are returned as null.
Here is the kvs list (where the first KeyValue was merged with the other 5
KeyValues):
### KVS Key:
\x00\x09\x00\x00\x00\x04\x00\x00\x00\x00\x07\x011c\x00\x00\x01B\xE2\xE0\x0C\xEF\x04,
Family: 1, Qualifier: c, Value: ^@^@^@3
### KVS Key:
\x00\x09\x00\x00\x00\x04\x00\x00\x01a\x97\x011j\x00\x00\x01B\xE2\xE0\xF0\x9D\x04,
Family: 1, Qualifier: j, Value: niutpzbmnewnfsowrlauxeda
### KVS Key:
\x00\x09\x00\x00\x00\x04\x00\x00\x01a\x97\x011n\x00\x00\x01B\xE2\xE0\xF0\x9D\x04,
Family: 1, Qualifier: n, Value: ^@^@^@^@
### KVS Key:
\x00\x09\x00\x00\x00\x04\x00\x00\x01a\x97\x011o\x00\x00\x01B\xE2\xE0\xF0\x9D\x04,
Family: 1, Qualifier: o, Value: ^@^@^@^@
### KVS Key:
\x00\x09\x00\x00\x00\x04\x00\x00\x01a\x97\x011p\x00\x00\x01B\xE2\xE0\xF0\x9D\x04,
Family: 1, Qualifier: p, Value: ^@^@^@^@
### KVS Key:
\x00\x09\x00\x00\x00\x04\x00\x00\x01a\x97\x011q\x00\x00\x01B\xE2\xE0\xF0\x9D\x04,
Family: 1, Qualifier: q, Value:
nbdpcwgwriaysaiqgkfozcacvalqymmuybsaoodidnbbltioqh
kvs length: 6
I tried to look further inside the code of Result.getValue and I noticed
that this line:
int pos = Arrays.binarySearch(kvs, searchTerm, KeyValue.COMPARATOR);
is returning -2 to the last 4 KeyValues in the kvs list, and that's why I
was getting those values as null.
(If I do not merge the first KeyValue the pos is returned correctly)
Why does this happen? What am I doing wrong?
Thanks.
